|Jason Pontin: Can technology solve our big problems? - TED.com|
In 1969, Buzz Aldrin’s historical step onto the moon leapt mankind into an era of technological possibility. The awesome power of technology was to be used to solve all of our big problems. Fast forward to present day, and what's happened? Are mobile apps all we have to show for ourselves? Journalist Jason Pontin looks closely at the challenges we face to using technology effectively ... for problems that really matter.

|Dimitar Sasselov: How we found hundreds of potential Earth-like planets - TED.com|
Astronomer Dimitar Sasselov and his colleagues search for Earth-like planets that may, someday, help us answer centuries-old questions about the origin and existence of biological life elsewhere (and on Earth). Preliminary results show that they have found 706 "candidates" -- some of which further research may prove to be planets with Earth-like geochemical characteristics.
